DIY eGPU experiences

[useafo]

Hi,

It seems that the problem is gone when I uninstalled the latest card driver, It left me with Video Controller driver, see the picture below and tell me what to do next. My eGPU is EVGA GTX 460 SE.

Use Setup 1.x to set G1 (Gen1) speed on the port. Then install Nvidia Verde driver.

Which version?

[kizwan]

Any version from here. Preferably latest version available in the page. Don't forget to set G1 (Gen1) speed using Setup 1.x.

My laptop has windows 7 32-bit, should I download 32-bit version only or is it ok to download a 64bit version?

Also, can I install an official verde graphic driver from nvidia.com ?

And I have read that you can make your own nvam.inf , how?

So I got my parts and tried to set up with setup.1 for x4. I have all mPCIe ports plus express port going. Things seem to go fine until I need to chainload then it goes to a black screen then i need to hit power button to restart. I think something with the MBR is messing it up. I did the query option in grub and it says I have fd0, hd0, and rd. I have a c drive and a second partition D: which is a recovery one. So not sure what the fd0 is? but any help with be appreciated. I tried to look at the grub web site help but much of it seems over my head. Thanks and hope to get my x4 working soon.

He has a series 5 chipset, so setting gen1 shouldn't matter since he can't do the 5.0 rate anyway. I really have no idea why he's getting BSODs.

I recently solved the BSOD problem by removing graphics driver that was installed by windows driver search and by doing what kizwan had told me, can you please answer my questions above?

Thanks in advance.

Only the 32bit version will work. You can install desktop drivers 285.62 and later as is with no modded .inf and you get full functionality.

Hi i have a Samsung R480 Laptop
Specs:

Intel Core i5 - 520M (First Gen)
GT 330M (1GB)
4GB ram

Can i make DIY eGPU setup consisting of a gtx 460?? Will it have better performance than my current GPU??

No one yet has done an EGPU on that laptop, so you'll need to find out your TOLUD and what ports are available. Your internal GPU is a bit weak, but not terrible. I'm pretty sure that you do not also have an intel igp, so you'll need to do x2 for good performance out of an EGPU.

To check your TOLUD, open up your device manager. Click "view", then "resources by connection", and then click "memory". Post a screenshot for us to look at to determine your TOLUD. TOLUD has to be 3.25GB (0xD0000000) or lower to add an egpu.

Determining if you can do x2 is a bit more involved. You'll have to download AIDA64 and move around your wireless card and determine which port numbers are available including the expresscard slot if you have one. AIDI64 reports port numbers under "motherboard", "chipset", "southbridge". You need either 1 & 2 or 3 & 4 to be available for x2.
